Abstract
BACKGROUND The incidence of chronic myeloid leukemia (CML) increases with age, but it is unclear how the characteristics of the disease vary with age. In children, where CML is very rare, it presents with more aggressive features, including huge splenomegaly, higher cell count and higher blast cell percentage. PATIENTS AND METHODS To investigate if after childhood the disease maintains or loses these characteristics of aggressiveness, we analyzed 2784 adult patients, at least 18 years old, registered by GIMEMA CML WP over a 40-year period. RESULTS Young adults (YAs: 18-29 years old) significantly differed from adults (30-59 years old) and elderly patients (at least 60 years old) particularly for the frequency of splenomegaly (71%, 63% and 55%, P < 0.001), and the greater spleen size (median value: 4.5, 3.0 and 1.0 cm, P < 0.001). According to the EUTOS score, that is age-independent, high-risk patients were more frequent among YAs, than among adult and elderly patients (18%, 9% and 6%, P < 0.001). In tyrosine kinase inhibitors-treated patients, the rates of complete cytogenetic and major molecular response were lower in YAs, and the probability of transformation was higher (16%, 5% and 7%, P = 0.011). CONCLUSIONS The characteristics of CML or the host response to leukemia differ with age. The knowledge of these differences and of their causes may help to refine the treatment and to improve the outcome. CLINICAL TRIAL NUMBERS NCT00510926, NCT00514488, NCT00769327, NCT00481052.

Abstract
BACKGROUND A prospective, single-arm, open-label, nonrandomized phase II combination chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) plus radioimmunotherapy trial was conducted to evaluate the efficacy and safety in untreated elderly diffuse large B-cell lymphoma (DLBCL) patients. PATIENTS AND METHODS From February 2005 to April 2006, in our institute we treated 20 eligible elderly (age > or =60 years) patients with previously untreated DLBCL using a novel regimen consisting of six cycles of CHOP chemotherapy followed 6-10 weeks later by (90)Y ibritumomab tiuxetan. RESULTS The overall response rate to the entire treatment regimen was 100%, including 95% complete remission (CR) and 5% partial remission. Four (80%) of the five patients who achieved less than a CR with CHOP improved their remission status after radioimmunotherapy. With a median follow-up of 15 months, the 2-year progression-free survival was estimated to be 75%, with a 2-year overall survival of 95%. The (90)Y ibritumomab tiuxetan toxicity included grade > or =3 hematologic toxicity in 12 of 20 patients; the most common grade > or =3 toxic effects were neutropenia (12 patients) and thrombocytopenia (7 patients). Transfusions of red blood cells and/or platelets were given to one patient. CONCLUSION This study has established the feasibility, tolerability, and efficacy of this regimen for elderly patients with DLBCL.

Abstract
The aim of this study was to evaluate the safety and efficacy of liposome-encapsulated doxorubicin citrate (LEDC) in patients affected by recurrent/metastatic gynecological malignancies scheduled for palliative chemotherapy. Inclusion criteria were proven recurrent/advanced gynecological neoplasms, measurable/assessable disease, adequate organ function, left ventricular ejection fraction >50% as determined by echocardiography, informed consent. LEDC was administered intravenously over 1 h at the dose of either 75 mg/m(2) or 60 mg/m(2) (every 3 weeks until disease progression or toxicity prohibiting further therapy). From May 2003 to September 2005, 36 patients were enrolled. Primary disease was ovarian, endometrial, and cervical cancers in 15 (42%), 11 (30%), and 10 (28%) patients, respectively. LEDC was employed as third- or fourth-line chemotherapy in 25 (70%) and 11 (30%) patients, respectively. The median number of courses of LEDC received was 3 (range 2-9). Six patients (17%) achieved a partial response to treatment lasting 27 weeks and 10 patients (28%) experienced stable disease lasting 18 weeks. The predominant toxicity was hematological, especially neutropenia. Among patients receiving a dose of 75 mg/m(2), two (11%) suspended therapy for febrile neutropenia, and nine (50%) required a dose reduction of 25%. As a result, the next 18 patients were treated at a reduced dose (60 mg/m(2)) of LEDC. Severe neutropenia (G3-G4) was significantly less common in this group (61% versus 22%; P= 0.04). LEDC has shown antineoplastic activity in previously treated recurrent/metastatic gynecological cancer patients and the toxicity profile could be considered acceptable at a 60 mg/m(2) dosage.

Abstract
Achieving a complete cytogenetic response (CCgR) is a major target in the treatment of chronic myeloid leukemia (CML) with interferon-alpha (IFN-alpha), but CCgRs are rare. The mean CCgR rate is 13%, in a range of 5% to 33%. A collaborative study of 9 European Union countries has led to the collection of data on 317 patients who were first seen between 1983 and 1997 and achieved CCgRs with IFN-alpha alone or in combination with hydroxyurea. The median time to first CCgR was 19 months (95% CI, 17-21; range, 3-84 months). At last contact, 212 patients were still alive and in continuous CCgR; 105 patients had lost CCgR, but 53% of them were still alive and in chronic phase. IFN-alpha treatment was discontinued permanently in 23 cases for response loss, in 36 cases for chronic toxicity (15 are still in unmaintained continuous CCgR), and in 8 cases because it was believed that treatment was no longer necessary (7 of these 8 patients are still in unmaintained continuous CCgR). The 10-year survival rate from first CCgR is 72% (95% CI, 62%-82%) and is related to the risk profile. High-risk patients lost CCgR more frequently and more rapidly and none survived more than 10 years. Low-risk patients survived much longer (10-year survival probability 89% for Sokal low risk and 81% for Euro low risk). These data point out that a substantial long-term survival in CCgRs is restricted mainly to low-risk and possibly intermediate-risk patients and occurs significantly less often in high-risk patients.

Abstract
BACKGROUND AND OBJECTIVES Idiopathic thrombocytopenic purpura (ITP) induces thrombocytopenia by means of an autoimmune mechanism. Despite the available therapies a subset of patients develop chronic refractory severe thrombocytopenia (i.e. a platelet count consistently lower than 20 to 30x10(9)/L), and life-threatening bleeding can occasionally occur. It has been suggested that the risk of major bleeding is higher in elderly patients and in patients with bleeding at diagnosis. However, since clear data on the influence of clinical and/or laboratory parameters on outcome are lacking, some patients may be receiving unnecessary treatment. DESIGN AND METHODS We made a retrospective analysis of a series of 310 patients with chronic ITP (108 males and 202 females), with a median age at diagnosis of 40 years (range 8-87 years). The median follow-up time was 121 months, (range 7-434 months). Therapy was most often started in the presence of hemorrhagic complications and/or a platelet count <30x10(9)/L either at diagnosis or during follow-up. RESULTS Our findings confirmed that patients who were symptomatic at diagnosis were more likely to have bleeding during their follow-up. Moreover, all the patients who suffered major bleeding during their follow-up had median platelet counts of 10x10(9)/L (range 1-20) at that time. Only one patient, aged 43 years, died of hemorrhage following prolonged severe thrombocytopenia. Age >60 years was not associated with any significant differences in incidence of bleeding at diagnosis or during follow-up. INTERPRETATION AND CONCLUSIONS We conclude that prospective studies are required to evaluate whether it may be reasonable to treat only symptomatic patients, independently of age.

Abstract
BACKGROUND AND OBJECTIVES The most common translocation in chronic myeloid leukemia (CML) t(9;22) (q34;q22) produces the BCR/ABL fusion gene. We set up and evaluated a rapid and reliable real-time reverse-transcription-polymerase chain reaction (RT-PCR) approach using TaqMan technology for detection and quantification of bcr-abl transcripts in CML patients at diagnosis and during therapy. DESIGN AND METHODS A pair of primers and probe complementary to ABL exon 2 were designed, enabling detection of the most frequent bcr-abl transcripts, and also of the normal ABL-Ia transcript as an internal control. Conditions were established to amplify less than 1(-10) target molecules/reaction and detect one CML cell in 10(6) cells from healthy donors. To determine the utility of the assay, we quantified the bcr-abl/ABL-Ia ratio in 59 bone marrow samples (45 samples with evidence of different Ph+ chromosome percentages and 14 samples in complete cytogenetic remission) from 48 CML patients, 34 of them at diagnosis and 14 in clinical remission (CR). In 14 cases, this ratio was compared with results obtained by a competitive-quantitative RT-PCR/capillary electrophoresis method from contemporary specimens. RESULTS By real-time RT-PCR, the median value of bcr-abl/ABL-Ia ratio at diagnosis was 15.334 (range 3.3-28.81) and fell to 0.9 (range 0.003-26.1) in CR. The median value of bcr-abl/ABL-Ia ratio at cytogenetic remission was 0.7 (range 0.003-2.83). The real-time bcr-abl/ABL-Ia ratios correlated with those obtained by competitive RT-PCR (p < 0.0001) and the percentage of Ph+ metaphases (p < 0.0001). The high sensitivity and specificity of the real-time RT-PCR procedure was confirmed in all 14 patients with minimal residual disease. INTERPRETATION AND CONCLUSIONS. We conclude that this real-time RT-PCR procedure is a reliable and sensitive method of monitoring CML patients after therapy, and that the bcr-abl/ABL-Ia ratio correlates strongly with cytogenetic analysis.

Abstract
BACKGROUND AND OBJECTIVES Recent advances in the treatment of multiple myeloma (MM) include use of high-dose chemoradiotherapy followed by allografting. Although allografting with bone marrow (BM) or peripheral blood stem cells (PBSC) seems to improve clinical outcome and lengthen survival, only about 50% of patients reach stringently defined complete remission (CR), and most subsequently relapse. We assessed the clinical relevance of minimal residual disease (MRD) in 14 MM patients in CR after allografting with PBSC (6 patients) or BM (8 patients). DESIGN AND METHODS Among the 30 out of 72 MM patients in our Institute who achieved CR after allografting, 14 had a molecular marker suitable for allo-specific polymerase chain reaction (PCR) analysis. Stringent molecular monitoring was done using clonal markers based upon rearranged immunoglobulin heavy-chain genes. Molecular remission (MCR) was defined as two consecutive negative PCR results. RESULTS Seven of 14 (50%) molecularly monitored patients, achieved MCR and did not relapse after a median molecular follow-up of 60 months (range 36-120). Median time to obtain first PCR negativity was 12 (BM group) and 6 months (PBSC group), respectively. Of the seven patients (50%) who never achieved MCR, one relapsed. INTERPRETATION AND CONCLUSIONS In conclusion, 50% of the MM patients in CR studied by us also achieved stringently-defined MCR. MCR was associated with a very low rate of clinical relapse.

Abstract
We studied nine patients affected by chronic myeloid leukemia (CML Ph+ and bcr-abl positive) and treated with alpha-interferon (alpha-INF) in order to: first, to evaluate the feasibility of a mobilization of peripheral blood stem cells induced by granulocyte-colony-stimulating factor (G-CSF) and the contamination by Ph+ cells and second, to quantify the amount of bcr-abl leukemia associated transcript by a quantitative assay during mobilization procedures, and post mobilization follow-up. Eight achieved a complete karyotypic remission before mobilization obtained with discontinuation of alpha-INF for few days and G-CSF at a dosage of 15 microg/kg/day for 5-7 consecutive days. By quantitative-competitive polymerase chain reaction (QC-PCR) assay, all the leukaphereses and bone marrow samples during post mobilization follow up were studied to determine the amount of bcr-abl transcript. Karyotypic and molecular analysis on evaluable leukapheresis showed that all the harvests were Ph negative and bcr-abl positive: in seven cases the levels of bcr-abl transcript were higher or equal to the pre-apheresis status. In three out of four patients, who underwent more than one leukapheresis procedure, we noticed a decreasing amount of bcr-abl contamination from the first to the last apheresis. Our results suggest that in patients who achieved a complete or major cytogenetic conversion with alpha-INF, it is possible to obtain a sufficient amount of PBSC for autografting by leukapheresis following priming G-CSF therapy and that the amount of neoplastic transcript does not seem to increase.

Abstract
PURPOSE To assess the clinical relevance of minimal residual disease (MRD) in patients with multiple myeloma (MM), 50 patients were monitored while they were in complete clinical remission (CCR) after autologous or allogeneic stem-cell transplantation. PATIENTS AND METHODS Stringent molecular monitoring using clonal markers based on rearranged immunoglobulin heavy-chain genes was performed in 44 of 50 MM patients in CCR. Molecular clinical remission (MCR) was defined as more than one consecutive negative polymerase chain reaction (PCR) test result. RESULTS Twelve (27%) of 44 molecularly monitored patients achieved MCR; four of the 12 became PCR-positive, and one of these four relapsed. In comparison with patients who did not achieve MCR, patients who achieved MCR had a significantly lower relapse rate (41% v 16%; P <.05) and longer relapse-free survival (35 v 110 months; P <.005). Fourteen of 26 patients in CCR who had received allografts were evaluated on a molecular basis: seven (50%) of the 14 achieved MCR and did not relapse; one of the seven remaining patients relapsed. Thirty of 47 patients in CCR who received autografts were evaluated on a molecular basis: five (16%) of the 30 achieved MCR; two of these five became PCR-negative, and one of these two relapsed. Ten of the 25 remaining patients later relapsed. For these nonrandomized groups, the higher MCR rate after allograft procedures was statistically significant (P <.01; Fisher's exact test). CONCLUSION MCR can be obtained in a relatively high proportion of MM patients who have achieved CCR after undergoing allograft procedures and in a smaller fraction of patients after undergoing autograft procedures. In approximately one fourth of MM patients who achieve CCR after transplantation, it may be possible to keep the disease burden constantly below the PCR threshold. Because MCR was associated with prolonged relapse-free survival, these patients could have a relatively favorable clinical outcome.

Abstract
BACKGROUND AND OBJECTIVE We further characterized a novel type of chimeric BCR-ABL mRNA transcript detected in a patient with Philadelphia chromosome positive (Ph+) chronic myeloid leukemia (CML). DESIGN AND METHODS We used reverse-transcription polymerase chain reaction (RT-PCR) and sequence analysis of the fusion region of the amplified cDNA fragment. Western analysis was performed on total protein. RESULTS Part of exon e8 of the BCR gene was joined to an intronic sequence of ABL intron Ib spliced on exon a2 of the ABL gene, giving rise to an in-frame e8-int-a2 BCR-ABL transcript. Only part of exon 8 of the BCR gene (e8) (intra-exonic break) was retained. The consequent BCR-int-ABL transcript was translated into a BCR-ABL protein of 1804 amino acid residues with a molecular mass of 197.5 kilodaltons (kDa) called p200 BCR-ABL. The 3' part of bcr exon 8 recombined within or alongside Alu elements at the additional sites. Sequence motifs similar to consensus binding sites of the lymphoid-associated TRAX and translisin proteins were present on both participating strands at 22q11 and 9q34 recombination sites, respectively. No differences in clinical or laboratory findings at diagnosis were found between this patient and CML patients with bcr-abl fusion. INTERPRETATION AND CONCLUSIONS The presence of Alu sequences and of the translisin binding motif on both sides of the breaks in this novel translocation suggests a possible general mechanism of molecular recombination in CML patients.

Abstract
BACKGROUND AND OBJECTIVE Autologous blood stem cell transplantation (ABSCT) using chemotherapy-induced mobilization of peripheral blood stem cells (PBSC) is being increasingly used in the treatment of multiple myeloma (MM). We report the clinical and molecular follow-up of 10 MM patients who underwent autologous stem cell transplantation with peripheral blood selected CD34+ cells, as support therapy following a myeloablative conditioning regimen. DESIGN AND METHODS The CDR-III coding region of the IgH gene was studied by a) consensus PCR applied to 8 MM patients, or b) by direct sequencing of PCR product generated by family-specific primers in the remaining two patients (who became immunofixation analysis (IF) negative). In this case, two patient-specific primers were generated, thus obtaining a high PCR assay sensitivity and specificity (ASO PCR). RESULTS Seven patients are alive: 4 of them have serum M protein assessable by IF, while 1 was not a secretor and 2 converted from serum IF positivity to negativity 6 and 12 months after ABSCT. Three patients died: 1 from disease progression and 2 from infective complications during clinical remission. The molecular analysis during the follow-up showed that the bone marrow samples from the two patients who obtained IF negativity were persistently PCR positive for the presence of rearranged CDR-III region. Moreover, despite the remarkable reduction of myeloma burden, a minimal level of residual myeloma cells was still detectable by molecular analysis. INTERPRETATION AND CONCLUSIONS These results confirm that although positive selection of CD34+ cells markedly reduces the contamination of myeloma cells from apheresis products by up to 3 log, and provides a cell suspension capable of restoring normal hematopoiesis after ablative conditioning regimen, it does not abrogate myeloma cell contamination in most of the apheresis products.

Abstract
BACKGROUND AND OBJECTIVE Capillary electrophoresis (CE) has become an attractive alternative to SLAB gel analysis for direct and accurate detection of amplified product, and a few cycles of polymerase chain reactions (PCRs) could be sufficient for both quantitative and qualitative analysis. We try to assess: 1) whether CE could be a practical, non-isotopic method for direct detection of the presence of amplified bcr-abl obtained by a reverse transcription (RT)-PCR (qualitative analysis) and 2) whether it is possible to quantify PCR products using a competitive RT-PCR measuring peak areas of CE electropherograms (quantitative analysis). DESIGN AND METHODS The two types of bcr-abl chronic myelogenous leukemia (CML) associated transcript products were generated by RT-PCR (qualitative analysis) from 1 microgram of total RNA extracted from bone marrow samples of 34 CML patients at diagnosis (median age 47.5; range 18-65; median Sokal's score 0.9; range 0.53-2.78). The PCR products were analyzed by SLAB-gel electrophoresis (SGE) on 2% agarose gels and by CE (128 runs; median 3.3 times for each sample). Furthermore, we assessed the amount of PCR product (quantitative analysis) by a competitive RT-PCR approach and by CE (bcr-abl transcripts were expressed as transcript per microgram of total RNA examined). RESULTS CE separation of PCR products obtained by qualitative RT-PCR showed baseline resolution for the two peaks corresponding to the two types of bcr-abl junctions: the b2-a2 type (343 base pairs, 10 patients) was revealed at 9.33 min [standard deviation (SD) = 0.1] and the b3-a2 type (418 base pair, 24 patients) at 10.03 min (SD = 0.25). By quantitative analysis we found that there is great interpatient variability in bcr-abl expression at diagnosis: the median value of the amount of bcr-abl transcript was 78,000 bcr-abl transcript/microgram total RNA ranging from 17,300 to 750,000. The amount of bcr-abl transcript at diagnosis was related to the number of blast cells (mean value 128,859 vs. 331,722 in patients with 0% blast cells and > 1% blast cells, respectively; p = 0.004) and Sokal's score (mean value 156,865 vs. 408,800 in patients with Sokal's score < 0.8 and > 1.2, respectively; p = 0.003). INTERPRETATION AND CONCLUSIONS Our results confirm that CE analysis offers greater resolution and enhanced sensitivity for detection and quantification of bcr-abl PCR product in the study of this leukemia. Qualitative analysis by CE of bcr-abl product provides a rapid technique (less than 20 min) for the analysis of subnanogram amounts of DNA fragments. CE run times are short, the capillary can be re-used and full automation may be feasible with data acquisition by a computer-controlled step. Competitive/quantitative analysis of bcr-abl as analyzed by CE allowed fewer reactions and more precise quantification.

Abstract
The activity of fludarabine monophosphate (FLU) and alpha-interferon (alpha-IFN) in low-grade non-Hodgkin's lymphoma (LG-NHL) and B-cell chronic lymphocytic leukemia (B-CLL) has been demonstrated in several clinical trials. In a study of 137 previously treated patients, of whom 77 had B-CLL and 60 with LG-NHL, we used FLU as salvage chemotherapy. Dosages of 25 mg/m2 were given in 30-min infusions for 5 consecutive d. Treatment was repeated every 28 d depending on the patient's clinical status for a maximum of 6 cycles. Entrance to the alpha-IFN maintenance portion of the study depended on patient response to initial FLU. All patients who had obtained a complete or partial response after the FLU therapy were randomized to receive alpha-IFN or no further therapy. The alpha-IFN dose was 3x10(6) units 3 times per wk until disease progression. At 4 yr with a median follow-up of 22 months the percentage of patients with persistent response ranged between 20% and 30% among all the responders. Thirty-five (45%) B-CLL patients achieved major responses (complete/partial response), as did 29 (48%) of those with LG-NHL. Among the 64 patients who achieved a good response to initial therapy and who have entered the second part of the trial, there has been a rate of prolongation of remission in favour of maintenance alpha-IFN (p=0.02). FLU therapy is an effective drug inducing remission in pretreated B-CLL and LH-NHL patients. However, as with other therapeutic modalities, remission is rarely maintained beyond 2 yr. So far, maintenance alpha-IFN has not been shown to produce significantly longer remission after treatment with FLU in LG-NHL, and there is no trend towards prolonged remission in B-CLL patients. The role of FLU needs to be further evaluated in the management of lymphoproliferative disorders by introducing it in combination with other drugs (alpha-IFN) in the induction phase and in maintenance treatment.

Abstract
In 141 adult patients with diagnosis of acute myeloid leukemia the overall expression and intensity of expression of CD34 antigen on leukemic cells was investigated. Myeloid blasts were tested by applying direct immunofluorescence staining using anti-CD34 fluorescein monoclonal antibody in flow cytometry. CD34 antigen was found in 73 out of 141 (51%) cases and in particular in M0, M1 and M4 French-American-British (FAB) cytotypes, while M3 and M5 cases were rarely positive. In patients whose blasts expressed CD34 antigen a significantly lower rate of complete remission (CR) was observed as opposed to CD34 negative cases (61% vs 88%) (P = 0.001). Furthermore, a negative correlation between high intensity of CD34 expression, measured as a mean fluorescence index (MFI), and CR rate was observed. In particular, patients with a higher CD34 fluorescence intensity (MFI > 23), showed a further reduction in CR rate (48%). Also, these patients had a significantly lower overall survival (P = 0.03) as compared to patients with no expression of CD34 and patients with CD34 MFI < 23. In conclusion, these findings confirm that CD34 expression is frequently associated with "immature" FAB cytotypes (M0, M1 and M4) and with a reduced probability to achieve CR. Furthermore, a high CD34 intensity of expression should be considered as a reliable poor prognostic factor.

Abstract
BACKGROUND One hundred sixty-eight peripheral T-cell lymphomas (PTCLs) were reviewed according to the Revised European-American Lymphoma (R.E.A.L.) Classification. PATIENTS AND METHODS The cases, originally diagnosed on the basis of the Updated Kiel Classification (UKC), were all provided with histological preparations, immunophenotype, clinical information, and follow-up data. The slides were reclassified by five observers, who integrated the R.E.A.L. criteria with cell size measurements. The prognostic value of clinical and pathologic findings was assessed by univariate and multivariate analysis. RESULTS The R.E.A.L. Classification was reproducibly applied by all of the observers. Clinically, anaplastic large cell lymphomas (ALCLs) differed from the remaining PTCLs by mean age (29.5 vs. 52.9 years), bulky disease (52.3% vs. 11.3%; P = 0.000), mediastinal mass (52.7% vs. 32%; P = 0.004), and disease-free survival (68.0% vs. 38.2%; P = 0.0001). Although each histological type displayed specific clinical aspects, PTCLs other than ALCL were basically characterised by a poor clinical outcome which was not influenced by the UKC malignancy grade. At multivariate analysis, the risk of a lower complete remission rate was related to bulky disease (P = 0.001), histologic group (non-ALCL) (P = 0.01), and advanced stage (III-IV) (P = 0.0002). CONCLUSIONS The present study supports the classification of T-cell lymphomas proposed by the R.E.A.L. scheme.

Abstract
We have developed a rapid, non-radioisotopic PCR fingerprinting technique for analysis of the HLA-Class II DQA gene second exon polymorphism, and have applied it to DNA samples from 210 healthy individuals. The technique is based on the formation of specific patterns (fingerprints) of homoduplexes or heteroduplexes between in vitro amplified DNA sequences. After electrophoresis on non-denaturing polyacrylamide gels and ethidium bromide fluorescence or silver staining, different HLA-DQA types give allele-specific banding patterns. HLA DQA typing is done by visual comparison between the sample's fingerprint patterns and appropriate controls. Similar fingerprints can be resolved by mixing the sample with a standard DNA in an amplified 'DNA crossmatch'. This application of PCR fingerprinting is useful to confirm the HLA-DQA serological typing and to improve the molecular characterization of this polymorphic region.

Abstract
The authors critically review the concept of anaplastic large cell lymphoma (ALCL). In particular, they provide the guidelines to the morphologic identification of the four main varieties of the tumour: common, giant-cell-rich, lympho-histiocytic, and Hodgkin's-like. The phenotypic and molecular characteristics of the neoplasm are discussed with special emphasis to those which can assist in the differential diagnosis between ALCL and Hodgkin's disease. Finally, the clinical features are presented along with the results obtained in the course of long-term prospective therapeutical trials.
